Suppose I have following document indexed in ES
{
Column1 : "Value1",
Column2 : "Value2
}
Later if there is a change in document and Column2 is deleted. How can I
use the Update API to delete this particular field ? All the examples that
I found on net talk about adding a new field, or updating value of a field
in JSON document.

Reindex would require the application to get the full new document. Since
in my case the changes are incremental (like delete a field or add a
field), I will have to re-read the full contents to reindex.
I found following update operation which can remove a field from the
document. It uses script to do this. My questions is can this be done
without script using pure Java API. The reason I am trying to avoid script
is because it is disabled by default.
We can also remove a field from the document:
curl -XPOST 'localhost:9200/test/type1/1/_update' -d '{
"script" : "ctx._source.remove("text")"
}'
